Aizen
Open-source macOS workspace that runs agents, terminals, and browsers per branch
Aizen is an agent-first macOS workspace for parallel development. It runs agents, terminals, files, and browsers side by side across every branch. It supports Claude, Codex, Gemini, and other ACP agents, and you add MCP servers from the app. It is open source and runs on Apple Silicon only.
Use it to run one agent for each branch without terminal clutter. It needs an Apple Silicon Mac.
Why it is here. It is an open-source option among parallel agent workspaces.
- Open source
- Branch-parallel agents
